Does the Radeon HD 4250 have dedicated ram or shared?

post #1 of 4
Thread Starter 
I have an hp dv6 3019wm first question is anyone know why it won't boot on battery, plug power in, boot it up, unplug power runs fine or battery?

New issue The Radeon HD4250 is lacking. I was able to play Hawken at any resolution just set the Unreal Engine ScreenPercentage to like 35% for 35fps in game not bad. Looks horrible though but playable.

Anyway I believe the hd 4250 uses the 4gb ddr3-1333 system ram and that may be the primary bottleneck.

I was going to pick up the Phenom II X940 Black Edition Quad, and 8gb of ddr3-1866 but if you can tell me more about the AMD ATI RS880M chipset that would be great!

Thanks

The card has onboard memory (the base base model has 128MB I believe) but when it runs out it can use up to 512MB of your system memory.

Thanks yeah i see it's at 320MB now on 4gb ddr3-1333.

Any chance of faster ram?

im gonna buy the phenom II x940 black edition quad... i wonder if i can adjust the multi in amd overdrive...

I saw what appeared to be a memory chip by the gpu on the board.

System memory speed is supported primarily by the memory controller on the CPU and the limits of the motherboard BIOS options, not by the memory itself. You can buy faster memory, but it is unlikely that it will actually run any faster on the laptop because it's unlikely to support higher speeds anyway. The highest "official" supported speed for the Phenom II X2 in your laptop is 1333MT/s. I would be very surprised if the BIOS supported any higher multiplier settings but you can always try. Unfortunately, it won't make any tangible difference in performance because the HD4250 is just a monumentally slow GPU no matter how fast the memory connected to it is. The HD4250 is based on 2008 GPU technology, and only contains HALF the shaders of the slowest discrete AMD GPU made at that time. There's no point trying to performance tune it. It's hopeless.


The Phenom II X940 will probably be slower than the X640 in older games anyway. More slower cores is not necessarily an upgrade.
